Is this it? Is my GF finally not mad at me anymore?

We had an argument about a week ago, we cut contact because she said she wanted 2 weeks to let things "calm down". But yesterday, out of the blue, she sent me a text thanking me for sending a card to her grandparents and then telling me how much they appreciated it.

A little later on I got another text asking "Are you OK? How was your trip back to Bristol?"

We had a nice conversation. Do you think she's over the argument and not mad at me anymore?
